Abstract
PCT No. PCT/AT94/00192 Sec. 371 Date Jun. 5, 1995 Sec. 102(e) Date Jun. 5, 1995 PCT Filed Dec. 9, 1994 PCT Pub. No. WO95/16063 PCT Pub. Date Jun. 15, 1995The invention is concerned with a process for the production of cellulose moulded bodies, particularly films and fibres, by extruding a solution of cellulose in a tertiary amine-oxide through a shaping device, for example a spinneret, and conducting the extruded moulded body while drawing it into an aqueous precipitation bath, in which it coagulates, whereafter the coagulated moulded body is washed with an aqueous washing liquid, characterized in that the precipitation bath employed for coagulation and/or the washing liquid employed for washing contain(s) a surfactant in dissolved form.
